Specification of Letters Patent.

Patented June 17, 1919.

Application filed. April 2, 1918. Serial No. 226,214.

To all whom it may concern:

Be it known that I, JAMEs T. JOHNSON, a citizen of theUnited States, residing at Chicago in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Die-Stocks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to die stocks, and has for its object the improvement of the construction of a simple and eflicient die stock that is susceptible of receiving different size dies, and which is provided with a series or" work holders arranged in a true line with the axis of the stock, and provided with retaining plates holding dies in pockets at right-angles to each other.

Another object of the invention is to provide work holders upon the body of the die, which are spaced from the body to a certain extent, whereby the operator may look into the body and readily discern how the work is progressing.

With these and other objects in View, the invention consists of certain novel construe tions, combinations, and arrangements of parts as will be hereinafter fully described and claimed.

In the drawings:

Figure 1 is a view in side elevation of a die holder constructed in accordance with the present invention. I

Fig. 2 is a view, in side elevation, taken at right-angles to the view shown in Fig. 1, and showing particularly an end view of one of the handle holders.

Fig. 3 is a vertical sectional" view taken on line 3-3, Fig. 1. V V

Fig. 4: is a view, in side elevation, of the die turned so as to place the handle holders in vertical position, they being shown in Fig. 1 in a horizontal position.

Fig. 5 is a perspective view of one of the holder plates.

Referring to the drawings by numerals, 1 designates the body of the die holder, and 2, 2, the handle holders or collars that are integrally connected to the body 1 by means of the legs 3. The inner end of the holders 2 terminate short, as at 4, of the body 1, so as to leave an opening, as clearly shown at 5, Fig. 2, to permit the operator to look inside of thebody 1.

The work holder's each comprises a sleeve annular collar-portion 6,- that is late grally connected to the body 1 through the medium of the legs 7, which legs 7 are si1nilarly constructed to the legs 3 of the handle holders 2. Like holders 2, the holders 6 terminate short of the bodyl, leaving open- 1 ings 5, so that the operator can look into the body 1, when a die is operating upon the work tosee how the die 8 is progressing with reference to cutting the threads on the inner end of the pipe or tubing that is inserted in the holders 6.

Referring to Fig. 3, opposite faces of the body 1 are provided with a square flange 9, that acts as a guide to retain the die 8 in pockets 9 (Fig. 3) formed on opposite sides of the body 1. I preferably employ two detachable holder plates 10, the specific structure of which plates is clearly illustrated in Fig. 5. Each plate comprises a body 11 angular in cross-section, and each body is provided at its ends and at its middle with apertured ears 12, each ear having an inwardly-depending portion 13 (Fig. 2) and a flat inner face 14, which inner face ll rests fiat against a similar face formed upon the foot portion 15 of some of the legs 7. The feet-portions 15 of the leg 7 are provided with threaded sockets, and to secure the plates 10 upon the body 1, I employ screws 16.

When it is desired to insert a die 8 into the body, I first remove one of the plates 10 and then drop or force the die into the particular pocket 9 formed at the base of the work holder 6, and then by placing plate 10 on the body and screwing the screws 16 into the sockets of the feet-portions 15, the holder plate 10 will be secured in place, retaining the die in position; each plate 10 is adapted to hold a die in either one of two sets of pockets, there being four pockets 9 at opposite sides of the inner face of the body, constituting four sets, and each set being adapted to receive a die, and two sets of pockets being closed at their contiguous ends by means of a single retaining plate 10.

Suitable handles 17 are retained in the handle holders 2.

By reason of my improved structure, a very simple and efi'icient die stock is produced, since the work can be examined through the open structure of the entire device, and, further, each work holder 6 is centered on a true line with the axis the entire holder, so that whileany one of sev difi'erent size may be upon, yet a very efficient and satisfactory piece of Work will be produced.

What I claim is:

In a die stock of the class described, the combination of a square body provided with legs upon all of its sides, handle holders integral With some of the legs and at opposite sides of the body, Work holders integral With some of the legs and being arranged around four sides of the body and .at right angles to the handle holders, said body provided With die receiving pockets formed under the Work holders and at right angles to each other, some of sald legs provided with feet having threaded sockets, a

die retaining plate angular in cross section provided with apertnred lugs adapted to ensignature.
